Substantially longer cutting lifeNitro-carburized flute has increased Rockwell hardness & will out perform cobaltCuts harder material
The flatter point takes a smaller chip. This allows drilling Into material with hardness over 30 on Rockwell scale.Stops drill walking
The split point design gives accurate starting without the use of a center point.Holds tighter holes
Split point design is self centering. This limits the normal oversize drilling characteristics.
